On my new to me XB12XP, came with what looks like a D&D Exhaust. Can't seem to find these on their or any other website so I am assuming they are no longer available? Is there a comparable product that can withstand jacking up the bike, or is there a way to jack up the bike with non-jackable exhaust? Currently I use a automotive floor jack and wheel chocks to switch out wheels and tires etc...
